FIELD: invention refers to seismic and acoustic prospecting of the regions covered with water and may be used for warning about the waves of tsunamis arising due to lifting and sinking of significant masses of the ocean.
SUBSTANCE: system for definition of the vibrations of water surface has microbarographs spaced on fixed distances along the coastline. The microbarographs are switched through the comparison scheme to the alarming system. Additionally the system for definition of the vibrations of water surface has a memory block, a control point and two correlators.
EFFECT: increase of reliability of definition of the vibrations of water surface.
